History
The truth is that we don’t know for a fact who invented the burrito or why. We know that they were invented sometime in the 20th century and that there are many theories about their creation.
One theory is that Juan Méndez, a street vendor in Chihuahua, Mexico, invented the burrito. During the Mexican Revolution in the 1910s, Méndez decided to wrap his food in flour tortillas to keep it warm and transport it on his small donkey. He then realized that wrapping the food in a tortilla was tasty and a good way to serve it

Why is it Called a Burrito?
The word translates to “little donkey”, stemming from “burro” which means donkey, and “-ito” which means little.
